No, this requires that the old Agent is uninstalled first.
When the agent is successfully installed, a unique auth-token is added to the registry.
This auth-token is associated with the supplied email and used to identify the agent when it communicates with the SecTeer VulnDetect backend servers. The auth-token will remain until the agent is uninstalled.
Upgrading will always preserve the existing auth-token.
In order to get a new auth-token, and associate the agent with a different account, the agent must be manually uninstalled, and then the admin can deploy the MSI, which will create a new auth-token that is associated with the correct account.
